decidedly unlike the cooperi female.^ 
Wheeler gives the distribution of Aphomomynnex as 
Ethiopian and Myrmelachista as Neotropical, but this is 
no proof the former could not occur in the New World trop- 
ics, especially as the fauna of that region is far from ex- 
haustively studied. Moreover, Menozzi (1935) descril>ed 
a Neotropical Aphomomyrmex nearly twenty years ago, 
so it is not unknown from this side of the Atlantic. And 
the genus which Dr. Brown proposes, Neaphomus, has been 
regarded as a subgenus of Aphomomyrmex. 
In view of the above discussion, therefore, and particular- 
ly since we are as yet unable to associate the worker caste 
with the female of the species concerned, I submit the 
following correction, and the synonymy then should i*ead : 
Aphomomyrmex (Neaphomus) cooperi (Gregg), nevv 
combination for Camponotus (Myrmostenus) cooperi

^ In contrast. Dr. Brown l)clieves, “there is no essential difh i. n<“« in 
the clavation of the antennae between cooperi and certain hinDnim 
.‘species. In fact, cooperi may be said to have stronger and nimf definite 
clavation of the funiculi than does M. (D.) pndercwskii femalm Purtlc r- 
more, certain species of Myrmelachista (eg. M. skwarrae) arc Muallf'r 
replicas of Ah goetschi in all essential habitus characters, including the 
lengthened head. Thus, while to Creighton some Myrmelachista females 
ma}' look like Indomyrmex of the same caste . . ., at least .som< h.n e 
an a])pearance very much different from that of iridomyrmex."
